Eq. I from Sol. 38, and the poles of the system lie at
the roots of this equation. 39 2 —=
s+3s+4 0
s_—3:l:x/9—39_—3i\/302,
_‘2—_7 7 Since the real part of both roots is negative, the system
is stable. Since the imaginary part is nonzero, the out—
put will oscillate. Oscillations are characteristic of an
underdamped system. Answer is A. 44. A baud is a unit of data transmission speed roughly
equal to one bit per second. The measure was named af—
ter the French engineer J ME Baudot and was initially
used to measure the speed of telegraph transmissions.
Bands were used to measure modem speed until the
early 1990s. At the lower model speeds available then,
the baud rate generally equaled the rate of transmis-
sion in bits per second (bps). Higher modem speeds are
generally measured in kilobits per second (Kbps). Answer is D. 45. The code is an example of a function call. A func-
tion call is similar to a subroutine except that a function
always returns a value to the calling program. A func—
tion is usually called implicitly by embedding the func-
tion call into another statement in place of the returned
value rather than having a separate call statement. Answer is B. 46. Professionals may provide services even if conﬂicts
of interest are involved as long as they disclose the con-
ﬂicts of interest and any inﬂuences and biases such con—
ﬂicts may cause. Answer is C. 47. It is ethical to receive compensation from more
than one party if all parties agree to the arrangement. Answer is D. 48. Political contributions can be made if not intended
to inﬂuence awards or achieve favor. Answer is B . 49. While (A), (C), and (D) are always ethics viola~
tions, an engineer is responsible to publicize conﬁdential
information about a product or process if not doing so
could jeopardize the welfare of society. Answer is B . 50. Although ethical obligations to an employer are
important, providing a safe, quality product to the con-
sumer and client that will not jeopardize the welfare of
society comes before any responsibilities to an employer. Answer is A. 51. While employers, societies, and all engineers should
work to ensure ethical behavior, ofﬁcial regulation is
provided by state agencies. Answer is D. 52. Whistle blowing is the act of telling news agencies
or regulating boards about ﬂaws in a design or proce-
dure that could jeopardize the public welfare. It is the
ethical responsibility of all engineers, although it is not
career-enhancing. Answer is A. 53. Compensation is not a reason for ethical behavior. Answer is B. 54. Clients are not required to seek competitive bids.
In fact, many engineering societies discourage the use
of bidding to procure design services because it is be—
lieved that competitive bidding results in lower—quality
construction. Answer is B. 55. iannual = (1 + imonthly)12 - 1
= (1 + 0.012)12 — 1
= 0.1538 (15%)
